摘　　要：城市轨道交通工程是投资大、施工周期长、影响面广的综合项目。由于线路一般设在人流密集的城市建成区,且沿街道路埋地(地铁)或架空(轻轨)铺设,因此在建设期间对城市的交通、环境及市政管道的影响较大。由于地铁车站、区间等工点的覆土通常为2～6 m,占地面积大,一般采用明挖施工,这对同处于浅层地下空间的重力流污水管道的影响很大。该文通过分析轨道交通工程建设对污水管网系统迁改建设、运行等方面的影响,结合部分典型设计案例,提出优化建议及措施,可供同行参考。An urban rail transit project is the comprehensive project with the great investment,long construction period and wide influence.The rail transit line is generally constructed in a crowded urban built-up area,and the line will be buried(metro) and overhead constructed(light rail) along the streets and roads.Therefore,it has a larger impact on the urban traffic,environment and municipal pipelines during its construction.Since the covering soil of the subway stations and the regions is usually 2 ~ 6m,and the covering area is larger,the excavation method is generally used in the construction,which has a large impact on the gravity flow sewers at the same shallow underground space.The article analyzes the impact of rail transit engineering construction on the relocation construction and operation of sewage pipeline network,and according to some typical design cases,puts forward the optimization proposals and measures.
